Summary: Microplastics are a major concern for the environment, being found globally due to industrial production and plastic debris degradation. They are small in size, less than 5 mm, and can exist in soil and aquatic ecosystems at micro and nanometer scales. They can have diverse chemical compositions, including potentially toxic additives. The research shows that Chironomus riparius, an aquatic dipteran species, is able to ingest microplastics and it affects the metabolism of these organisms. However, the understanding of the molecular-level effects of microplastics on invertebrates is still limited.

Summary: This study investigated early Cd contamination across five generations of the model organism Chironomus riparius using spiked water exposure scenario. Results showed that exposure to brief and low Cd concentrations can affect all measured endpoints, with initial Cd pollution detected after just five consecutive generations. Importantly, fertility was greatly impaired at 100 μg/L of Cd after three generations. PGR calculation proved to be a sensitive tool for monitoring early pollution of Cd, and no adaptation to Cd was observed over five generations.

Summary: The study aims to characterize the bacteriobiota associated with the gut of C. riparius larvae, compare it with potential sources of gut microbiota, and assess its ability to degrade cellulose, proteins, and different types of microplastics. The metabarcoding approach revealed Proteobacteria, Firmicutes, Bacteroidota, and Actinobacteriota as the most abundant bacteria in the gut samples. Culturable microbiota analysis identified several common species and demonstrated their ability to grow on different types of microplastics and exhibit cellulolytic and proteolytic activity. The characterized strains show promise for environmentally friendly degradation of organic pollution and microplastics in freshwater ecosystems.

Summary: Several studies have shown that ingestion of microplastics has negative effects on aquatic organisms, including sediment-dwelling invertebrates. This study explores the interactive effects of exposure to polyethylene microplastics on the life history traits of midges, taking into account different temperatures, salinity levels, and food availability. The results reveal that microplastics' effects can be stronger at lower temperatures or severe food shortages, and that toxicity induced by microplastics is reduced under warmer temperature and salinity conditions.

Summary: The increasing concern about the adverse impacts of wildfires on the environment has been raised by their magnification in recent years. Wildfires are recognized as a significant source of pollution for nearby aquatic systems and can be toxic to aquatic life. However, the impact of different severity origins of ashes on aquatic biota at the sub-organismal level has not been assessed. This study evaluated the molecular response of Chironomus riparius exposed to low and high severity ashes from burnt Pine plantations, revealing that wildfire ashes significantly disrupt the environment and have genotoxic, apoptotic, endocrine disruption, detoxification, and stress response effects on aquatic organisms.

Summary: Sulisobenzone (BP-4) is a commonly detected UV filter in aquatic ecosystems with suspected endocrine disrupting effects. Exposure to environmentally relevant concentrations of BP-4 in gilt-head sea bream resulted in disruption of energy and lipid metabolism, oxidative stress, and impacts on enzymes involved in steroid and thyroid hormones biosynthesis. This integrated multiomic approach highlights additional modes of action of BP-4 that may have been overlooked by traditional single omic methods.

Summary: Environmental contamination reduces the quality of ecosystems and causes stress on organisms. Organisms can avoid continuous exposure to contaminants by moving to less disturbed areas. However, sporadic contact with contamination should not be ignored, as it increases stress. This study aimed to assess the stress levels of zebrafish under different contamination scenarios. The results showed that uncontaminated areas played a crucial role in alleviating stress for zebrafish in a chemically heterogeneous landscape.

Summary: The high contamination levels caused by pesticides make aquatic ecosystems vulnerable. Mobile organisms can avoid continuous exposure to contaminants by moving to less disturbed habitats. This study used a system called HeMHAS to evaluate the ability of Daphnia magna to detect and avoid habitats contaminated by specific pesticides. The colonization of habitats and chronic toxicity were also assessed for different parameters. The results showed that D. magna did not prefer less contaminated areas and did not move to highly contaminated zones. Additionally, exposure to a mixture of pesticides significantly prevented colonization, and negative consequences on survival, fecundity, and body length were observed with chronic exposure to a specific pesticide. The study suggests that the risk of local population extinction may be underestimated if only forced exposure endpoints are examined.
